Direct laser trapping of single globular DNA molecules

Nucleic Acids Symp Ser. 1999:(42):99-100. doi: 10.1093/nass/42.1.99.

Abstract

We show herein that a single T4 phage DNA molecule which was transformed from coiled to globular state, was trapped directly by Nd:YAG laser (1064 nm). We also estimated trapping force of globular DNA molecules.
